RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 772,107, dated October 11, 1904.

Application. ned August 6,1904. sensi No. 219,714. (No model.)

To all whom, it may concern.:

To this end the invention consists in the pe-i culiar construction of some of the parts, tof gether with their particular arrangement, as hereinafter more fully set forth in the following specification, and clearly illustrated in the accompanying drawings, in which- Figure l shows a side elevation; Fig. 2, a vertical cross-section through fr, Fig. l, enlarged, of my improved device. Fig. 3 is a longitudinal section on y y, Fig.` l.Y

Referring more particularly to the drawings, the numeral 1 designates the rail, and 2 an insulating-body in sheet form, of any suitfVVV able non-conductingmaterial, adapted to rest against the under side of thejtread of the rail,

close to the sides of the web and over the base.

The numeral 3 designates the fish-plate, between the inner face of which and the web of the rail the insulating material is placed. These plates are not provided with the usual bolt-apertures, but are held in position by means of a device about to be described.

The numeral 4 designates a spring-clamping plate. This plate has a curved central body portion 5, which bears against the plate 3 about midway of its length. The ends 6 of this plate 4 are bent at about right angles to the curved center portion and then again at right angles to said bend. These angled ends are capable of being drawn yagainst the rail and are adapted to inclose the {ish-plates 3 and prevent any longitudinal movement thereof.

The rails are formed with a plurality of boltholes 7, as are the ends 6 of the plates 4, which holes are adapted to register with those in the rail and to be held by suitable bolts 7. A sheet of suitable insulation is interposed between the angled ends of the plates 4 and the ends of the fish-plate 3, and this insulation also extends to the eXtreme ends of the plate 4 between the ends 6 and the rails. Suitable insulating rings and washers 8 are also located between the bolts and the plate ends 6. A set-screw 9 is located in the plate 4 about midway of its length, provided with a jam-nut 10. The insulation between the rail and the fish- `plate extends beyond the ends of said plate and reaches to the extremity of the springclamping plate 4. When the bolts 7 are drawn up tight, the setsere w 9 is drawn against the fish-plate and locked with the nut 10. This action will take up any play that may eX- ist and will tend to lock the bolts 7 more securely.

It is obvious that the outside of the rail may Abe provided either with a solid single-piece plate 11, properly insulated, as shown Vinthe Y drawings, orthe spring-'clamping plate may be `applied to both sides, ifV desired. When the single-piece platell is used, its innersurface is slightly curved to insure its bearing against the web of the rail.

The present device may be used with equal facility for an ordinary rail-joint-that is, one in which the insulation is not required. I

Having thus fully described my invention,

what I claim, and desire to secure by Letters `Patent, is-

In an insulated rail-joint, the combination with a rail, a sheet of insulating material secured to and in contact with each side of the rail-web beneath the tread and on the upper face of the base, of a fish-plate, a curved spring-clamping plate having angled ends between which said {ish-plate is held, a set-screw in said spring-plate adapted to bear against the center of said fish-plate, a jam-.nut on said set-screw, a suitable insulating material interable insulating rings and Washers between said bolts andthe ends of said spring-plate, all substantially as described. IO

In testimony whereof I have afxed my signature in the presence of two witnesses.
